I wonder if anyone has used Piriform Defraggler. On my XP Desktop and Laptop it seems no better than the windows built in one. On my Vista Home Premium it was still hard at it after 12 hours and showing 29%. I defragged using windows prog which took about 1 hour, tried Piriform again and it was still no better. Any comments would be appreciated.
Thanks all for your comments. I am familiar with Diskeeper and Auslogics. I was curious why when using Vista it took so long on a previous de-fragged disk, it is also my belief that it is no better than the bog standard windows tool, which leaves much to be desired.
